Abstract

The aim of this paper to investigate the different schemes of matrix converter under R-L load condition and also to obtain maximum voltage transfer ratio of matrix converter. Matrix converter is a new type of direct AC/AC converter, which converts input line voltage into variable voltage with unrestricted output frequency without using intermediate circuit, DC-link circuit, pure sine-in and pure sine-out is the unique feature of the matrix converter. But maximum voltage transfer ratio of matrix converter is limited to 50%. This is the major disadvantage of matrix converter. This limitation can be overcome by eliminating third harmonics by injecting third harmonic voltage in the input voltage; the maximum voltage transfer ratio 100% is achieved. This paper also analyzes the basic operating principle and simulation modeling of different schemes of matrix converter such as 1. Two phase to single-phase matrix converter. 2. Three phase to single-phase matrix converter. 3.Three phase to three phase matrix converter using PSPICE software.

最大电压转换比矩阵变换器的不同方案分析

本文的目的是研究在R-L负载条件下矩阵变换器的不同方案，并获得矩阵变换器的最大电压传递比。矩阵变换器是一种新型的直接AC/AC变换器，它在不使用中间电路、直流链路电路的情况下，将输入线路电压转换成输出频率不受限制的可变电压，纯正弦输入和纯正弦输出是矩阵变换器的独特之处。但矩阵变换器的最大电压传递比限制在50%以内。这是矩阵变换器的主要缺点。这种限制可以通过在输入电压中注入三次谐波电压来消除三次谐波来克服;最大电压传递率达到100%。本文还分析了矩阵变换器的基本工作原理和不同方案的仿真建模。两相到单相矩阵变换器。2. 三相到单相矩阵变换器。3.三相到三相矩阵变换器使用PSPICE软件。
